範例
程式碼編輯器 (JavaScript)
var empty = ee.Array([], ee.PixelType.int8());
print(empty.bitwiseOr(empty)); // []
print(ee.Array(0).bitwiseOr(ee.Array(0))); // 0
print(ee.Array(0).bitwiseOr(ee.Array(1))); // 1
print(ee.Array(1).bitwiseOr(ee.Array(0))); // 1
print(ee.Array(1).bitwiseOr(ee.Array(1))); // 1
print(ee.Array(0xFF).bitwiseOr(ee.Array(0xFFFF))); // 65535
print(ee.Array(0xFFFF).bitwiseOr(ee.Array(0xFF))); // 65535
print(ee.Array(-1).bitwiseOr(ee.Array(0xFF))); // -1
print(ee.Array(-2).bitwiseOr(ee.Array(-3))); // -1
print(ee.Array(-2).bitwiseOr(ee.Array(-4))); // -2
print(ee.Array([6, 6]).bitwiseOr(ee.Array([1, 11]))); // [7,15]
